German scientists have suggested that cutting 30 percent of the daily calorie intake improves memory function in the healthy elderly.
According to a study published in the Proceedings of the National Academy of Sciences, individuals who reduce their calorie intake have sharper memories and think faster.
Diets low in calories but rich in unsaturated fatty acids such as the Mediterranean diet are reported to be beneficial for brain function and reduce the future risk of Alzheimer's.
The calorie restriction is believed to boost memory through reducing insulin resistance and inflammation, linked to age-related cognitive decline.
Scientists are optimistic that their findings will pave the way for the development of new methods to tackle age-related cognitive decline.
